Carnets vs REPL

Jupyter notebooks are a powerful tool used in education and research. You can write small snippets of Python code and observe the result on screen, combine with paragraphs of text, using Markdown. Carnets provides a complete, stand-alone, implementation of Jupyter notebooks. Everything runs on your device, using the embedded Python interpreter; you do not need an internet connection. You can chose between Jupyter notebooks and the more advance Jupyterlab using Settings. Numpy, Sympy, Matplotlib, Pandas, lxml, bokeh, nbextensions (including ipywidgets) and many other packages are pre-installed. To see the full list of installed packages, type "%pip list" in a code window. You can add more packages using "%pip install packageName", but only if they are pure Python. If you need scipy, seaborn or scikit-learn, please use our other App, "Carnets - Jupyter (with scipy)". You can share your notebooks with other apps and also open notebooks or directories managed by other apps. Partial list of installed packages: astropy, babel, bokeh, cryptography, cvxopt, Fiona, geopandas, geopy, lxml, matplotlib, numpy, openCV, pandas, pillow, pyFFTW, pyproj, rasterio, regex, shapely, sympy, wordcloud.

REPL is a native code runner for Python and JavaScript — built for the AI era. When your favorite AI gives you code, where do you test it? REPL lets you paste code directly from AI conversations, run it instantly, and copy the results back. No laptop required. FEATURES - Native Python 3.11 — Real CPython running locally on your device, not a web interpreter - JavaScript Engine — Powered by iOS JavaScriptCore - Persistent State — Variables survive between runs, like a true REPL - Share Sheet — Send code from any app directly to REPL - History — Access your last 50 code runs - Smart Parsing — Automatically extracts code from markdown fences - Offline — Everything runs locally, no internet needed - Dark Mode — Easy on the eyes BUILT FOR AI WORKFLOWS Copy code from ChatGPT, Claude, Gemini, or any AI assistant. Paste into REPL. Tap Run. See results. Copy output back to your conversation. Iterate faster than ever.
